[NSRCA-discussion] Heathkits

[steve hannah]

My Dad is Bill Hannah, who used to be the VP of Engineering for Heath
Company.  He was the one that introduced the RC equipment into the Heath
lineup.  As a kid I built A LOT of Heathkits.  I learned how to debug all
sorts of electronic problems and lead to my engineering career.  Of course,
I learned to fly on Heathkit radios.

Heath radios were a kit version of the Kraft radios.  They had some of their
own designs in the later years as well.

I believe the engineer you are talking about is Mike Geishin (SP?).  I'm not
sure of his exact title when he was at Heath, but he was instrumental in
their radio designs.  He flew with my Dad back in the day.

By the way, I still have the Heath stereo system I built when I was in high
school.  It survived the endless torment I subjected it to in my college
years.  Good stuff.

Steve Hannah.
